Question

The Editor-in-Chief of the student newspaper was doing a final review of the articles submitted for the upcoming edition. Of the 12 total articles submitted, 5 were editorials. If he liked all the articles equally, and randomly selected 1 article to go on the front cover, what is the probability that the chosen article is an editorial? Write your answer as a decimal rounded to four decimal places.

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

total articles = 12

editorials = 5

P (editorial) = ?

Step 02:

articles selected = 1

P (event) = favorable outcomes / total outcomes

P (editorial) = 5 / 12 = 0.4167

The answer is:

P (editorial) = 0.4167
